NOTES This is intended to be a high-resolution, elapsed (or wall) clock. See MPI_WTICK to determine the resolution of MPI_WTIME . If the attribute MPI_WTIME_IS_GLOBAL is defined and true, then the value is synchronized across all processes in MPI_COMM_WORLD . NOTES FOR FORTRAN This is a function, declared as DOUBLE PRECISION MPI_WTIME() in Fortran. SEE ALSO MPI_Wtick, MPI_Comm_get_attr, MPI_Attr_get 4/10/2026 MPI_Wtick(3)
